has any one used a square drive shaft in the mud or sand? seems like mud/sand could get in between the two tubes and start to wear the metal down after a while. /forums/images/graemlins/thinking.gif

Since you won't get a very balanced shaft with the square tube, I don't think you'll want to run them in the mud, sand, or anywhere that will call for high speeds. As for wearing them down, I don't think its worth worrying about. it would take a while to wear through 3/16 or 1/4 inch /forums/images/graemlins/dunno.gif
